If you're looking to maximize the amount of fat burned in your next workout, think about having a coffee half an hour before you get started.
Researchers found that 3 milligrams of caffeine per kilogram of body weight can raise the rate of fat burning during aerobic exercise. The coffee dose was shown to increase maximal fat oxidation rate (MFO，脂肪氧化率) by an average of 10. 7percent in the morning and 29 percent in the afternoon.
The recommendation to exercise on an empty stomach in the morning to increase fat oxidation is common. It is still unknown whether this increase is due to exercising in the morning or due to going without food for a longer period of time.
Caffeine is often associated with improved athletic performance, though the science behind this link isn't as comprehensive as it could be. In later cycling tests after the caffeine had been given, the fat-burning capability of the body was measured, showing the impact that caffeine had made on MFO. Maximum oxygen uptake was also raised, as was the intensity of exercise.
The results of the study showed that acute caffeine intake 30 minutes before performing an aerobic exercise test increased MFO during exercise regardless of the time of day. Overall, these results suggest that a combination of acute caffeine intake and exercise at moderate intensity in the afternoon provides the best scenario(方案) for individuals seeking to increase whole-body fat oxidation during aerobic exercise.
A. It is based on results gathered from 15 male volunteers.
B. However, this recommendation may lack a scientific basis.

D. A new study suggests it can make a significant difference to fat burning.
E. They are clear enough to suggest that there is some kind of association there.
F. Researchers have found that if cyclists take more caffeine, they will ride much faster.
G. Researchers were keen to look in detail at the relationship between caffeine and exercise.
